Love to know more about this audit regime with du in aircraft.
In NZ the airnz engineers get no mention of it in training (unless they ask the oldtimers). Also our government, green party, university senior prof's had no idea it was used. In a country that has clear legislation banning the entry into our ports of Nuke powered or armed vessels, and specifically prohibiting the transport of nuclear waste of any form through a 600km offshore zone. I find this situation crazy. By the way US hates NZ so much for this Legislation that they have refused to play wargames with us since it was introduced in 87. (Boo Hoo )
Suspect you may be able to supply us with some per area rad readings from these Aviation sized blocks?
